Guild Wars 2

So for the Feed the ghost achievement. You need to feed him 1000 candy corn.
But when i first fed him, i didn’t have 1000. So i fed him 200, thinking i’ll just give the rest later when i have it.

But now the npc is missing. And no there wasn’t a game update that messed it up. he;s simply vanished. But i’d really like to complete that achievement.

He appears and disappears. Not sure if it’s intended or there is a timer but just check his spot again after some time and you will find him eventually.
